I upgraded to 11.10 yesterday.
My Nautilus started to crash on load, looks like a known bug with remote terminal plugin nautilus exiting with segmentation fault after upgrade.
So I decided to uninstall it, but that was the beginning of my nightmare - my root password is changed.
Yes, I type in the right password, but auth fails!
I don't know what to do, I can't auth as root, which means I can't install/uninstall packages.
umpirsky@umpirsky:~$ su Password: su: Authentication failure
Any idea? Please help.
UPDATE: I removed default keyring, but problem resists.
